Arrange the following sentences in the correct order.

Arrange the following sentences in the correct order.
Options:
A. Researchers find more fossil remains of a species in younger geological layers than in older ones.
B. They discover that the younger layers contain sediments particularly favourable to fossil preservation.
C. The team therefore compares the frequency of several species across layers with different preservation conditions.
